PMMA Bathroom Sanitary Ware
문제 현상
Acrylic bathtub surfaces lose gloss and yellow, and fine cracks appear after wiping with cleaners
원인 분석
Sanitary ware is in long-term contact with cleaners, and strong solvent-type products induce stress cracking; hot water and load cycles cause failure in stress concentration areas; surface wear reduces gloss; during on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based only on experience
해결 방법
①Choose neutral PMMA-compatible cleaners; ②make the bathtub support structure uniform to prevent stress concentration; ③regularly polish to maintain the surface; after adjustment, take samples continuously to verify the effect, and resume mass production only after confirming stability
핵심 요약
The life of PMMA sanitary ware is determined jointly by chemicals and structure; neutral cleaning plus uniform support are maintenance essentials; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence
